uv pip install -r requirements.txt Fails to Parse Requirements

[merajhashemi]

Running uv pip install -r requirements.txt fails with a parsing error, while pip install -r requirements.txt works without issues.

requirements.txt content:

--editable '.[dev]'

Error Output:
Running uv pip install -r requirements.txt produces the following error:

error: Couldn't parse requirement in `requirements.txt` at position 11
  Caused by: Expected package name starting with an alphanumeric character, found `'`
'.[dev]'
^

However, pip install -r requirements.txt successfully installs the requirements.

uv version: 0.5.16

We don't support stringified dependencies like that. You can just remove the quotes -- they aren't needed in a requirements.txt file.

This is tracked in #3621.

Without the quotes uv pip works; however, pip fails with the following error:

ERROR: .[dev, is not a valid editable requirement. It should either be a path to a local project or a VCS URL (beginning with
 bzr+http, bzr+https, bzr+ssh, bzr+sftp, bzr+ftp, bzr+lp, bzr+file, git+http, git+https, git+ssh, git+git, git+file, hg+file, hg+http,
 hg+https, hg+ssh, hg+static-http, svn+ssh, svn+http, svn+https, svn+svn, svn+file).

I reckon this difference in behavior should be documented in the pip compatibility section.
